What is Curves to Mesh?

Curves to Mesh is an add-on for 3D modellers who want to create mesh surfaces from a network of bezier curves.  Once created, these can then be used alongside Blender’s core modelling tools to create more complex shapes.

Workflow

1. Create a set of bezier curves in Blender. There are three modes to choose from:
   
   • Surface to Mesh: Form a network of four separate curve segments to define a single quad-based surface.  These four separated curve segments can then be connected together with other curve segments to create a whole network of patches.💡 Important: The add-on detects corners where curves meet. A single closed curve (like a rectangle or polygon) won’t be recognised as a surface. For best results, split closed shapes into four separate curves before generating the mesh.
   • Profiles to Mesh: Create a set of curve cross sections to loft 3D shapes.
     
     
   • Sweep to Mesh: Create a set of curves along another curve to loft 3D shapes.
     
     
2. Preview the mesh in real-time as you edit the curves.
3. Convert the curves into a normal Blender mesh surface.
4. Use this regular mesh surface like any other alongside Blender’s traditional mesh modelling techniques to create more complex objects for export or rendering.

Features

• Additional options including mirroring, smoothing and control point snapping.
  
• Works on a variety of bezier handle types (Vector, Aligned, Free).
• Compatible with my other popular add-ons such as Flowify, Quad Maker and Conform Object.

Comparison: Loft Curves vs Curves to Mesh

You may wish to consider the Loft Curves add-on as an alternative to Curves to Mesh which comes in the form of an interactive modifier:

Feature/Workflow	Curves to Mesh (C2M)	Loft Curves (LC)
Core Focus	Patch based mesh generation (rectangular patches)	Loft/extrusion between 2+ curves
Modifier based	No	Yes
Creation Process	Preview -> Apply	Add Modifier through Loft Curves Panel
Guide Curves	No: Patch based	Yes: between profiles
Sweep/Profile Tools	Yes	Yes
Smoothing / interpolation	More advanced smoothing options	Basic Smoothing Options
Side-panel UI	Yes	Yes (for initial set up)
Best use case	Quad based surfaces from split curve patches	Organic, flowing shapes and flexible lofting
UV Map	Partial	Yes
Architecture	Python	Python + Geometry Nodes

Please Note!

• This add-on is not intended to be a full CAD tool and should be used with Blender’s existing modelling toolkit.
• The add-on assumes an understanding of using bezier curves, subdivision surface modelling and a working knowledge of Blender. 

How are the meshes created?

Meshes can be created from:

Single Curves:

An unfilled edge-loop mesh can be created from a singular curve. Curves can be cyclic (joined up in a loop) or non-cyclic.

4 sided Curve Surfaces:

A surface can be created by making a set of 4 curves that have their end points snapped to one another:

Curve Cross Sections:

A mesh surface can be created by joining curves together. Curves can be cyclic (joined up in a loop) or non-cyclic:

“Profiles to Mesh” mode:

“Sweep to Mesh” Mode:

Updates

Version 2.5.x: Curve ordering in Profiles to Mesh

By default, when in Profiles to Mesh mode, the order in which the curves are joined together is determined by how close they are to one another.  There is a new option where you can instead order the curves by Curve Name, which gives you finer control over the order in which the curves are joined.

The new option, called Bridge Ordering, is described in the documentation:

Ordering by Position (the default):

Ordering by Curve Name:

Reversed: When ordering by Curve Name, this reverses the order of the curves, in case the results appear incorrect (a minor Blender bug)

Version 2.5: Sweep Mode

The new “Sweep to Mesh” mode allows you to set up multiple curve cross sections and then extrude them along a guiding curve:

You can then create more sophisticated objects like rings and pipes:

Version 2.4: Performance improvements and UI tweaks

• This version should improve performance by clustering intersecting points together during calculation, rather than finding the distances between each point.
• There are also some minor changes to the UI, where I have moved some of the more advanced parameters into a separate section on the side panel, imaginatively called ‘Advanced’.

Version 2.3: Continuous curves

Now you no longer have to go through the trouble of splitting each curve at an intersection: Curves to Mesh will do this for you.

Version 2.2: Animation Nodes

There is now an additional feature that will allow you to use Curves to Mesh as a node in the freely available Animation Nodes Blender framework.

This will allow you to do the following key things:

• Dynamically edit the curves in realtime, which can be used as an alternative to the ‘Preview’ mode.
• Animate all the parameters for creating curve surfaces.

Also included is a zip file in the downloads section that contains a set of sample .blend files demonstrating this feature.

Version 2.0

This is a significant update which allows:

• The ability to create more sophisticated meshes such as cars, machine parts and even heads. Please note however that we do not recommend doing this instead of Blender’s existing toolset, as managing the curves can get quite complex.
• An interactive preview mode to work with the mesh as it is created in real time.
• The ability to mirror the curves.
• The option to control the resolution of the mesh from the curves.
• Automatic snap options that move the nearest vertices to control points.

The add-on is now exclusively integrated into Blender 2.8.

Please see the video tutorial here:

Version 1.0.3: Blender 2.8 Beta

I have now upgraded the add-on for 2.8 beta and put it ready for download alongside the 2.7 version. You will be able to tell the 2.8 zip file version because it ends in 2.8!  I’ll be updating the documentation once 2.8 becomes the main Blender release.

Blender 2.8 is still in beta, so if you have any problems with the add-on let me know.

Version 1.0.2

New Feature: You now have an additional option called Curve Profiles To Mesh which will allow you to select multiple curves and create a mesh from the edge loops. See the documentation for instructions.

Fixes: When selecting a curve that has multiple splines, such as the figure 8, the add-on did not create all the shapes.  This has now been fixed when selecting one curve object.
